App registration ID not generating in GCM Android

I have tried some forum pages and searched through stackoverflow for the same thing, but I did not find the solution.

I have used the below code to generate registration ID for GCM notification. But I get an empty string as a registration ID:

GCMRegistrar.checkDevice(this); GCMRegistrar.checkManifest(this);

if (GCMRegistrar.isRegistered(this)) { Log.d("info", GCMRegistrar.getRegistrationId(this)); }

regId = GCMRegistrar.getRegistrationId(this);

Log.v("log", " register id oslo : " + regId);

if (regId.equals("")) {
    // replace this with the project ID
    GCMRegistrar.register(this, "718437041388");
    Log.d("info", GCMRegistrar.getRegistrationId(this));
} else {
    Log.d("info", "already registered as" + regId);
}

Please help me with this, tell me if I got anything wrong.

Thank you in advance, Nirav.

Notice that

    GCMRegistrar.register(this, "...");

is asynchronous. Therefore, calling GCMRegistrar.getRegistrationId(this) immediately after that is not reliable, so you should avoid it.

The id will arrive via broadcast callback to your GCMIntentService, as a part of the registration procedure. from there you can than store the gcm key anywhere you like, and use it in other parts of the application (usually on the server).

Notice that GCMIntentService should be defined at the root package of your app for it to work.

You should not get the registrationId just after GCMRegistrar.register(this, "718437041388");
In fact, do you have a correct GCMIntentService.java which receive the regId?
If yes, you can get the regId from the onRegistered inside GCMIntentService.java 

 @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
        Log.d("GCMIntentService", "in GCMIntentService");
        displayMessage(context, getString(R.string.gcm_registered));
        ServerUtilities.register(context, registrationId);
    }
